Hi all on the list:
There have now been several posts here pointing
as a suitable crowbar circuit. I want to copy that
When searching for suitable components I could not
find a suitable opto-coupled Diac as shown in the
My HV transformer will draw abt. 21A of current so
I need a Diac able to withstand that or I have to
substitute that part with ??? A diac controlling
a thyristor ? Or ??
Are there any such diacs or what would a suitable
replacement circuit not altering speed too much
Thx for your help!
